I am building a telescope for the first time, and I had some questions. Most of them were answered on a separate thread which I will link, but I had one I forgot to ask. I am using Quiktube for the optical tube, and I need to paint it to stop light from bouncing inside to much. The problem is that the inside is waterproofed, so I am not sure how to paint it. Should I use a primer? And when I put the black paint on the inside, what is the best way to do it? It seems to me it would be really hard to paint the inside of a big tube, so I have been trying to figure out the best way to paint it. What have you guys used in the past?

Pick the edge and then peel the waterproof layer in a spiral.

Don rubber gloves and use a 'bent' paint brush taped firmly onto a stick.

Or saw the handle off a wider brush and stick a dowel or cane in a drilled hole in the head.

You can also use a small paint roller on a stick or cane.

Don't have sleepless nights when reading about having a hole in your head.

Reserve those for observing.
